To all whom it may concern: 1

Be it known that I, BENJAMIN E. GETZ, a

, citizen of the United States, aresident of Morton, in the county of T azewell and State,

of Illinois, have invented new and useful Improvements in Elevators, of which the following-is a specification.

This invention has reference to certain new and useful improvements in; grain elevators.

One of the objects of the. present invention is, to improve the construction of elevators which are built inside the crib, and

particularly those which are -called-one side elevators, viz." those built on one side of the drive-way extending through the crib..

The invention has for a further object, to position the leg 'of the elevator on oneside of the drive-way through the crib, so that th'ematerial dumped into the chute leading to the elevator boot, will be delivered in a direction transversely to the direction of movement of the lower run of the elevator,

and between the opposite vertical runs of the elevating means.

Built in elevators" have been of-several forms: one includlng legs 'on eitherside of *the crib driveway, the elevating means traveling down one leg,across and beneath the driveway and up the other leg,- thev material to "be elevated being dumped into a chute extending across the driveway and longitudinally of the lower run'ofthe ele vator; another including spaced legs located on one side of the driveway, the chute for the material being disposed transverselyofthe drive-way and arranged to transfer.

' material :to the elevating =means which travels'up one leg and down the other; andstill another and a' much preferredforin,

comprising a single leg located on one side-- of the driveway of the crib, the elevating means traveling down one side of the leg and up the other side, the chute being arranged transversely of the drive-way and transferring the material in the path of the elevating means.

The elevating means in eaoh ofthe various types of elevators mentioned,'comprises chains and buckets, and therefore, when the grain, whether shelled or on the cob, is

dumped into-the chute, it is transferred immediately in the direction of movement of v Specification of Letters iatent. fatented sept '1 9 2 0 Original application filed October 18, 1918, Serial hTo. 258,726. Divided and thisapplication 'filed .February 13, 1919. Serial 1\To. 276,702. 1

the buckets which cut their way through:

the material picking up a load and conveying it to a discharge spout atthe upper end.

of the leg. The buckets cutting through the grain destroyquantities of the loose grain and sheila large portion from off the ears wh ch is wasted. It is this feature of loss which I overcome with the use of my improved elevator and-its arrangement in the driveway of the crib. That the invention may be more fully understood, reference ishad to .theaccompanying drawings, in which:

Figure l is a front elevation of my im proved elevator, partly in section, a portion of the driveway of the crib being shown with a wagon in dotted lines preparatoryto dumping material into the chute; g

; Fig, .Z'is an end elevation of Fig. 1, partly insection, the viewlooking through the.

driveway, with the elevator on the side;

designates the floor of the driveway of. crib, afwago'n A'being, shownin dotted lines togive an idea of-thearrangement of the leg of the elevator on one side of the driveway, and the positionof the wagon when dumping the material to, be elevated and stored.;;:

QEXtendiing transversely across the "drive- W y nd beldwthe, floor; is a chute 2 into;

which the material in'the wagon is dumped.

and bylmeans of which the material is transferred toj the-boot: of the'el'evator. iAlso a-r'-- rangedfinth'e'driveway, but to one side and beneath' the-floor of- 'thecrib and, communiw T therebetween, at

powerfrom any suitable source and in any suitable manner. The lower end ofthe leg 4 is joined to a boot 9 located in the pit 3.

The lower runs of the chains 5 pass over idler sprocket wheels 10 and around floating sprocket rings 11, in the boot 9. Connecting the opposite sprocket chains 5 and suspended Suitable intervals, are buckets 12, which'have a scooping action in the boot 9 and between the sprocket rings 11, see Fig. 3. 7 As shown in Fig. 3, the sprocket rings 11 are of such a diameter as to cause a spreading out of the lower runs of the chains 5, so as to enable the buckets 12 to have a good sweep and scoop the material deposited in the boot 9. As shown, the material discharged from the chute 2 will pass I through one of the sprocket rings 11 into the path of the buckets 12, permitting the buckets'to scoop up the material, whether loose grain or corn on the cob without cracking the grain or shelling it. When the mate rial is discharged by the buckets at the top of the leg, it is received in a chute 13 and transferred to a hopper 14: on which is swiveled a suitable flexible spout 15 by means of which the material is distributed to proper bins in the crib.

As shown in the drawings, the up and down runs of the elevating chains 5 are immediately behind each other in a direction longitudinallv of the drive-way of the crib, and the chute 2 therefore, in the driveway, leads directly into the front of the boot.

Ordinarily, in constructions of this character, the material would be discharged into the side of the'elevator leg and down'upon the buckets, and the pressure of the material upon being discharged from the chute, to-' gether with the pressure of the buckets in another direction, not only cracks the shelled corn, destroying the same, but also shells thecorn from the ear, wasting it. All this is obviated by the use of the present construction.

The boot construction shown in Figs. 3 and 4 include a semi-spherical shaped receptacle 16 in which the floating sprocket rings 11 are carried, one wall of which is cut away, as at 17 to receive the dischargeend of the chute 2.

In Fig. 5 a modified form of boot is shown, the remainder of the structure being substantially as seen in Figs. 1 and 2. In this modified'structure the receptacle, designated 18, is preferably rectangular shape, one wall cut away to receive the chute 2. In place of the sprocket rings 11, a pair of sprocket wheels 19, suitably spaced apart,

are j ournale'd in the boot 9, 'saidsprocket wheels being so placed as to spread the lower runs of the chains 5, the material being dis-- charged into the receptacle 18 between the sprocket wheels 19 to be scooped up by the buckets. The construction of boot last described is a very suitable and eflicient boot, and one which may be manufactured at the minimum cost. r

This application is a division of the appli-Z cation filed by me on the 18th day of October 1918, bearing Serial Number 258,726.

What I claim is i 1. A crib elevator including a leg, a boot for the leg, an elevating chain in the leg having buckets thereon, a floating" sprocket wheel in the boot and around which the chain passes, said sprocket wheel being formed and arranged to spread the chain laterally and outwardly beyond each of the respective opposite sides of the flights of the chainto provide an enlarged open space,

idler sprockets above the floating sprocket and arranged adjacent thereto to restrict upward movement of the idler sprocket, and

means to discharge material into the boot 7 wheel;in the boot andaround which the chain passes, said sprocket" wheel being formed and arranged to spread the chain laterally and outwardlybeyond each of the respective opposite sides of the flights of the chain to provide an enlarged open space, means above the floating sprocket and adj acent each of the opposite sides thereof and engaged withthe chain flights to restrict upward movement of the idler sprocket, and means-to discharge material into the boot between said spread portions of the chain and in the said enlarged open space provided thereby.

In witness whereof,'I have hereunto aflixed myhand. I o
